Mrs. Williams believes that if she gives
students peppermints during the test that
they will perform better.
During the next test she gives
half the class peppermints and
half the class she does not.
What is the independent variable
in her experiment?

What will the student be measuring
(dependent variable) in this experiment?

She goes to Hedgehog Pond in the morning and
fishes for 4 hours. She then goes to Three Creek
Pond in the afternoon and fishes for 4 hours. Has
Amanda conducted a fair experiment? Why or
why not?
